I enjoy it for what it is. But Children of Men, Y Tu Mama Tambien were far better films for me personally. The director did some amazing work with making the mundane into art, and had some incredible shots.I love slow burn, slice of life dramas when paced well. But I agree that this one took it a bit too far with the long shots. I see the narrative and creative justification for them but at the same time think the film would've been better with a little less.
Good film though and I love how some of the major plot points and revelations that occured around Cleo, that didn't directly affect her own life, almost felt like part of the film's background than blatantly pointed out in the foreground. I think this style of directing eases the viewer into naturally feeling and seeing the world through Cleo's eyes.
But it all really doesn't do much but stand out like a pretty picture if you don't have the narrative chops to keep you motivated to sit through it.
